Broadcast Filtering

A switch can be configured to block massive transmission of broadcast packets being forwarded to every
port on the same VLAN. This is also known as broadcast storm protection. Failure to block broadcast storm
packets can cause a delay or halt to other data. Some switches allow you to select a Storm Control Rate for
each port, others assign a predetermined Storm control rate for all ports on the switch.

1. .Select System and click on the radio button for the switch you want to configure.
2. Select QoS > Broadcast Filtering. The QoS Broadcast Filtering screen displays.
3. Select Enable. If the selected switch supports configuring individual ports, a Storm control rate screen
will be displayed. If the selected switch does not support individual port configuration, all of the ports
will be set to a predetermined Storm control rate.
